The (apparently rotated) picture shows my badly scaled up automatic airvent valve just a few cm downstream from the pump. I have some water hammer (hydraulic shock) when the pump goes off and this scaled up air vent is my prime suspect. I am ready to drain the system down and screw this old vent off. By the look of the amount of nipple, I will have to cut the olive off, clean the pipe and replace with the new compression 15mm auto air vent.
What I don't know is what the object is immediately below the air vent sticking out to the left and whether I need to replace that too. Is it a manual bleed valve for example?
Thanks.
